MARIETTA, Ga. -- A Marietta man could face three centuries worth of jail time for 'gang loyalty' activities that included shooting at innocent motorists.

Cobb County District Attorney Vic Reynolds announced, Thursday, that a Cobb jury has convicted Johannes Alexander Lopez, 27, on 26 indicted counts, including 16 counts of violation of the Street Gang Terrorism and Prevention Act, four counts of aggravated assault, five counts of firearms possession and one count of criminal damage to property in the first degree.

The evidence showed that in the early morning hours of Sept. 15, 2013, Lopez - a member of the criminal street gang SUR 13 - was involved in two separate shootings of innocent residents who were fired upon merely because their cars were the color of one of SUR 13’s rival gangs.
